After having supported Control Data operating systems for 15 years with other companies, I was hired by CDC in the early 80’s. One of their software experts came into my cube the first day with a Peripheral Processor dump and asked me to look at it. After a couple of minutes, I looked up at him and said, “This has to be off a NOS/BE operating system.” He asked ,”Why?”, and I said, “Because no NOS proggrammer would even think to do code modification on the fly, but it’s done by NOS/BE programmers all the time.”
He said, “You passed the test.” We became best friends.
The only Control Data hardware I ever saw was a 10MB (5 internal, 5 removable) 14” hard disk drive used with my dad’s Alpha Micro system. A few years later he bought a 20MB Winchester drive the size of a VCR. It could fit inside the bottom of the CDC cabinet. It blew my mind.
